WATERPROOFING TISSUES- SPECIFICATION forming part of Letters Patent No.757,326, dated April 12, 1904.

' Application filed April 25, 1903. Serial No. 154,309. (No specimens.)

To all whom it may concern:

Be it known that I, THIEBAUD LUTHRINGER, dyer, a citizen of the Republic of France, residing at 149 Rue Moncey, Lyons, in the Republic of France, have invented certain new Improvements in Waterproofing Tissues, of .which the following is a specification.

This invention relates to a new process of waterproofing tissues composed of silk, wool, I cotton, pure or mixed, by employing solid and inodorous carbids of hydrogensuch as stearin, paraflin, spermaceti, &c.with sulfid of carbon as a dissolvent' for these materials and its evaporation in the presence of 5 gaseous carbonic acid.

To realize this new process of waterproof-- ing, the tissues, which have been previously dressed by the ordinary means, must be passed into a vat A, holding a solution of sulfid of carbon containing one or moresolid carbids of hydrogen, as explained above, then between rollers B, in view of expressing and returning to the vat the excess of the solution. At this time the tissue undergoes the action of the Waterproofing. When. passing out of the press or rollers, it is carried into a compartment or room D, where a fan running at great speed is placed directly below it and where is a current of gaseous carbonic acid emerging 3 from a recipient F, placed underneath'the fan. The power of this current will be regulated according to the nature of tissues to be treated. Above the tissue this compartment is shut up by a cover Gr, conducting the vapors of carbonic acid mixed with sulfid of carbon toa chimney, which mixture'prevents and avoids all danger that can happen in the use of sulfid of carbon alone. When coming out of the present compartment, the tissue is water- 4 proofed and dried and can be rolled directly around a roller J, worked by hand or mechanically at the speed required.

In order to completely remove all odor from the fabrics, the same may be made to pass, on emerging from the chamber D, into another chamber provided with afan or ventilator and undergo an energetic ventilation, driving away all odor.

In passing the material between the rolls 5 so that it can be inspected and to finally avoid \the escape of odors of sulfid of carbon the compartment L, in which the vatA is placed,

may be shut up by a glass cover C, which can be raised and lowered at will. There is a door to this compartment through which the vat containing the waterproofing solution is introduced.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. A new process of waterproofing threads and yarns for the weaving of textile fabrics such as silk, wool, cotton, pure or mixed,

which consists in submerging the textile material in a solution of inodorous carbids of hydrogen solids such as stearin, parafiin, spermaceti, &c., dissolved in sulfid of carbon, and in leading said textile material through a closed chamber, and exposing it therein to a current of carbonic acid gas, substantially as described.

2. A new process of waterproofing threads and yarns for the weaving of textile fabrics such as silk, wool, cotton, pure or mixed, which consists in submerging the textile material in a solution of inodorous carbids of hydro- 7 5 gen solids such as stearin, parafiin spermaceti, &c., dissolved in sulfid of carbon and in leading said textile material through a closed chamber and exposing it therein to a current of carbonic-acid gas, said gas being projected with force against the textile material by suitable ventilating means, substantially as described.

3. A new process of waterproofing threads and yarns for the Weaving of textile fabrics such as silk, wool, cotton, pure or mixed which consists in submerging the textile material in a solution of inodorous carbids of hydrogen solids such as stearin, paratfin spermaceti, &c., dissolved in sulfid of carbid, then removing the excess of solution from the textile material by pressure, and in leading said textile material through a closed chamber exposing it therein to a current of carbonic gas said gas being projected with force against the textile material by suitable ventilating means.

In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 11th day of April, 1903.

THIEBAUD LUTHRINGEE.
